What is a Slowed and Reverb Generator?
▼
A Slowed and Reverb Generator is an audio tool that reduces the playback speed of a song and layers it with spatial reverb effects, creating that dreamy, atmospheric "aesthetic" sound popularized on TikTok, YouTube, and SoundCloud. RankRax Tools offers a professional-grade version that runs entirely in your browser.
Is this tool completely free?
▼
Yes — 100% free with no hidden fees, no watermarks, and no account required. You can upload, remix, and export WAV files as many times as you like. RankRax Tools is built for music creators and enthusiasts who need professional results without paying for expensive DAW software.
Do you store or upload my audio files?
▼
Never. All processing happens locally inside your browser using the Web Audio API. Your files never leave your device and are never sent to any server. This ensures complete privacy — your music stays yours.
How do I make a slowed and reverb song for TikTok?
▼
Upload your track, set Speed to around 80–90%, reduce Pitch by 2–4 semitones, add 40–60% Ambient Reverb, and a touch of Echo Depth. Preview the result, then export as WAV. Import the WAV into CapCut, InShot, or TikTok's video editor to pair with your reel or short video.
What audio formats are supported?
▼
The tool accepts any audio format your browser supports — this typically includes MP3, WAV, OGG, FLAC, AAC, and M4A. Output is always exported as a high-quality, uncompressed WAV file for maximum audio fidelity.
What's the difference between reverb and echo?
▼
Reverb simulates the acoustic environment of a physical space — like the natural sound reflections in a large hall. Echo is a distinct repetition of a sound with a delay. In slowed + reverb music, ambient reverb creates depth and "dreaminess," while echo adds a subtle layered texture that makes the track feel immersive.
Can I use this for Lo-fi music production?
▼
Absolutely. This tool is widely used as a Lo-fi flip generator — a quick way to transform any track into a chilled, Lo-fi aesthetic version. Combine slow speed with high reverb and a warm bass boost for the classic Lo-fi sound perfect for study playlists, aesthetic YouTube content, and SoundCloud uploads.
Does changing speed also change the pitch?
▼
In traditional audio playback, yes — slowing down also lowers pitch. In this tool, Speed and Pitch Shift are independent controls. You can slow the tempo while keeping pitch natural, or lower the pitch separately for more dramatic effect. This gives you full creative control over both dimensions of the sound.
Is it legal to remix and upload slowed and reverb songs?
▼
Copyright rules depend on the original track's licensing. Songs you own or have licensed, royalty-free tracks, and Creative Commons music can be freely remixed and uploaded. For commercial songs, platform policies vary — always verify the original track's copyright status before distributing your remix publicly.
What are the best settings for an aesthetic slowed reverb sound?
▼
A popular starting point: Speed at 85%, Pitch Shift at -2 semitones, Bass Boost at 8–10 dB, Ambient Reverb at 50%, and Echo Depth at 15%. This produces the warm, melancholic, spacious sound characteristic of the slowed + reverb genre. Experiment from there to match the specific mood of your track.
